To draw/identify lines of symmetry in a 2D shape, you can follow these steps: ^{thirdspacelearning.com 1}

1. Locate the center of the 2D shape.
2. Draw a vertical line through the center and check for line symmetry.
3. Draw a horizontal line through the marked center and check for line symmetry.
4. Draw a line from each vertex through the center and check for symmetry.
5. State the number of lines of symmetry.

A line of symmetry is a line that divides a shape exactly in half. They can be found by folding a shape in half or using a mirror. Each side of the line of symmetry will look exactly the same. For example, a square has 4 lines of symmetry. Lines of symmetry look like dashed lines. ^{mathswithmum.com 2}
